Hurry home, grab a poop bag, and return to clean it up.
Look around for something to clean it up with. If you can't find anything, leave it, but feel guilty.
Pause to look at the poop, realize you can't do anything about it, and continue on your walk.
Poop bag? Why should I bring a poop bag?
Apologize for the annoyance. Invest in barking inhibitors until you find one that works. Check in with neighbors to see if there is a change.
Say you are sorry. Get a bark collar.
Ignore your neighbors. Give your dog more food.
Tell your neighbors to go to hell. Your dog is on your property.
Remain calm. Apologize while asking if the dog's owner is also hurt. Provide medical care if necessary and possible. Provide your contact information. Offer a ride to a vet.
Apologize. Provide your contact information.
Refuse your contact information until the other owner threatens to call the police. Then, give it grudgingly.
Tell the other dog's owner that it was her dog's fault and walk away.
It would never happen. I don't let my dog walk on other people's grass lawns.
Quickly hustle your dog to a non-grass area to finish urinating. Dog urine kills grass!
Isn't that what grass is for? Dogs to pee on?
Is my dog peeing? Whatever. Fuck your lawn.
Immediately grab the dog by it's collar/scruff and tell it "NO!" Apologize to the hiker and hold the dog until the hiker passes.
Tell your dog to knock it off. If it doesn't, yank it's collar/scruff and hurry it by the hiker.
Say, "Don't worry. He's friendly. Trust me!"
Say, "This trail's open to everyone. If you don't like dogs, don't come here."
Make a comfy bed for your pet on the floor and make sure he stays there.
Let the dog on the bed for a little bit, but cover it first with towels or other sheets.
You paid a fee for the dog to stay, so he can use the furniture as much as he wants.
Pet policy? I didn't read anything about a pet policy. C'mon, Fido! Up on the bed!
